How a Raymarine Autopilot Fits Together

A Raymarine Evolution pilot combines three core pieces. The EV sensor core senses heading and motion, an ACU actuator control unit drives the steering, and a drive unit or pump moves the rudder. Each ACU is matched to a drive type. The ACU-100 and ACU-150 suit smaller mechanical and hydraulic drives, while the ACU-200, 300, and 400 handle larger linear, rotary, and solenoid controlled steering. Match the ACU to your drive and steering system.

Picking the Right Drive

Drive choice follows your steering. Hydraulic reversing pumps and linear drives come in Type 1, 2, and 3 sizes rated to your displacement and steering load. For existing hydraulic steering, a solenoid valve and the ACU-300 work with constant running pumps. When replacing a component, confirm voltage, 12V or 24V, and that the drive matches your boat size and the rest of the pilot.

Frequently Asked Questions

What are the main parts of a Raymarine autopilot?

An Evolution pilot uses an EV sensor core for heading and motion, an ACU actuator control unit to drive steering, and a drive unit or pump to move the rudder.

Which ACU do I need?

It depends on your drive. The ACU-100 and 150 suit smaller drives, while the ACU-200, 300, and 400 handle larger linear, rotary, and solenoid steering systems.

What drive type fits my boat?

Drives come in Type 1, 2, and 3 sizes rated by displacement and steering load. Match the drive to your boat size, steering type, and the ACU you are using.

Do Raymarine autopilots come in 24V?

Yes. Many drives and pumps, such as reversing hydraulic pumps, are offered in both 12V and 24V. Confirm the voltage matches your boat.
